MAX213ECAI

Drivers, Receivers, Transceivers Overview

The MAX213ECAI is a single-supply RS-232 transceiver from the MAX202E–MAX213E family, manufactured by Analog Devices Inc./Maxim Integrated. It operates on a +4.5V to +5.5V supply and features four drivers and five receivers with full-duplex communication capability. The device supports data rates up to 120kbps under loaded conditions. It includes an integrated charge pump requiring four external 0.1μF capacitors. Key electrical parameters include ±15kV ESD protection (HBM), typical supply current of 20mA, and shutdown current of 15μA. The component is housed in a 28-pin SSOP package and functions within an operating temperature range of -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated high ±15kV HBM ESD protection on driver outputs and receiver inputs for harsh environments.
• Built-in charge pump circuitry enables single +5V supply operation without bipolar voltage requirements.
• Two receivers remain active during shutdown mode to monitor external activity while maintaining low power consumption.
• TTL/CMOS compatible logic levels with tight input thresholds ensure reliable signal detection.

• Battery-powered equipment
• Hand-held equipment
• Portable diagnostics equipment

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'CAI' against official manufacturer documentation to confirm pinout compatibility and electrical characteristics. Confirm that the required 0.1μF external capacitors are included in the system design. Ensure the ordering suffix matches the intended temperature grade and package variant before procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring two awake-in-shutdown receivers for remote wake-up or monitoring capabilities. Verify that the 15μA shutdown current meets the specific power budget constraints compared to other family members. Ensure the application requires the specific control pin polarities defined for the MAX213E variant.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX202E–MAX213E family of RS-232 transceivers designed for robust performance in demanding environments. The MAX213E variant specifically distinguishes itself by offering two receivers that function independently of the main shutdown state. This configuration supports applications where continuous line monitoring is necessary even when the primary system is powered down.

Drivers, Receivers, Transceivers FAQ

How does the MAX213E handle shutdown mode differently from other family members?

Unlike most family members where all receivers enter a high-impedance state, the MAX213E keeps receivers R4 and R5 active during shutdown to monitor external signals.

What is the propagation delay for the MAX213E receivers in normal operation?

The receiver propagation delay is typically 0.5μs in normal operation, increasing to 4μs when exiting shutdown mode.

What external components are required for the charge pump?

Four external 0.1μF capacitors are required to support the integrated charge pump circuitry for generating the necessary positive and negative voltages.
